i Specication of Letters Patent.

Patented Nov. 5, 1912.

Application filled March 29,. l1911'. Serial No. 617,731.

To all-whom it may concern. Be itkn'oWn that I, WILLIAM I-I. BEERY, a citizen of the United States, residing at Celina, in the county of Mercer and State of Ohio, have invented a new and useful Culvert-Mold, of which the following is a speciication.v v i It is the object of this invention to provide a mold for the fashioning of concrete structures, the construction ofthe mold being such that certain constituent parts thereof, remain in the completed structure, to serve as reinforcing elements therefor.

In this specification, I shall describe the mold as being employed for the formation of a culvert, the word culvert being employed in a loose and generic sense to indicate a Huid conducting element of any sort.

A further-object of the invention is to provide a culvertmold, parts of which are adapted to remain in the completed culvert, to serve as reinforcing elements therefor, the said parts being provided withmeans whereby the inner and outer laggings of the culvert may, be removably held in place during` the construction of the culvert.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in thedetails of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of what is claimed without depart-- ing from the s/pirit of the invention.

In the accompanying drawings,-I `igure l is a side elevation, parts being broken away; Fig. 2 is a. transverse section; Fig. 3 is a perspective of one form of the completed product of the mold.

The device forming the subject matter of this application, is adapted to be employed in fashioning culverts, of the sort. conm'ionly used in providing in a passageway for streams beneath highways and the like.

In carrying out the invention. a trench is first dug, in the line in which the culvert is If desired, a bed of concrete or the like, 'denoted by the numeral l. may be fashioned in the trench, longitudinally of the same. Upon this bed 1, when the same is used, a plurality of supports 2 are placed, the supports 2 being spaced apart, longitudinally of the trench.

-suftieient'lyg Each of t-he supports 2 consists of inner and outer circumferentially continuous members, the inner member being ordinarily a ring 3, and the outer member` being ordinarily a ring Ll, of considerably larger diameter than the ring 3. These rings 3 and 4 are united by radial connections, the same being ordinarily in the form of bolts or bars, shown at 5. A plurality of securing devices, ordinarily threaded bolts or studs 6, project outwardly from the outer rings 4.

ther securing devices, ordinarilv threaded bolts or studs, as aforesaid, project inwardly from the inner rings 3, as shown at 7 .In the interior of the inner ring 3. a lagging S, consist-ing of a plurality of sections, is disposed. Another lagging 9. likewise composed of a plurality of sections, is disposed npon the outside of the outer rings 4. The securing members and 7 extend through the laggings 9 and S, respectively, and nuts 10 are mounted upon the members 6 and 7, to hold the laggings in place.

In practical operation, the supports 2 are spaced a sutiicient distance apart. so that they will form the ends of each section of Beginning gings 8 and t) are mounted in place, the concrete l5 being inserted between the laggings, as the laggings are built up. Or.' if desired. the entire lagging S may be secured to the inner ring 3. successive sections of the outer lagging 9 being secured` to the enter ring 4, until-the top of the culvert is reached. During the building up'of the eulyert, longitudinal reinforcing' bars l2 are placed upon the connections 5 between the rings 3 and i. .\fter the concrete has setthe nuts l() are removed from the members t3 and 7. permittingthe laggings S and 9 to he removed. lVhen it `is desired to leave the flow-line of the culvert smooth, the operator ma \r pass within the culvert. and knock otl' with a cold chisel or thc like. inwardly lu'oiecting ends ot the securing lugs 7. In a similar manner, the prot-ruding ends of the bolts (i may be eut ott;

although the cuttingott" of the elements (i is. a. matter of minor consequence. since these elements do not protrude into the flow-line of the structure.

It will be seen that the connections 5 between the rings 3 and 4, together with the reinforcing bars l2, are inserted in theconadjacentY the bottom vof .the trench successlve sections ot the lagwel sttuent material of thelculvert, the ring 4e surrounding the outside 0f the finished culvert, and the ring 3 extending about thel body 14, surrounded upon the outside, at its ends, by the bands 4, and supported interiorly, adjacent its ends, by the bands 3, the` body llt. beingl braced transversely by the connections 5, and being braced longitudinallyby the rods l2. v

From the foregoing it will be seen that a culvert, of any Cross sectional contour, may berapidly .built up, in any desired lengt-hs,

:certain of the constituent elements of thel mold, in which the culvert is fashioned, remaining in the finished product, to serve as reinforcing elements therefor.

` In Fig, 1, the outer lagging' 9 is shown as terminating adjacent the sides of the bed 1, it being presupposed that it is desired to form the bed l and the culvert proper 15 as one monolithic structure. It will be clearly understood, however, without specic illustration, that the outer lagging 9 may be carried entirely around the circumference ofthe outer ring 4, whereupon the tubular structure, denoted specifically by the numeral 14 in Fig. 3, will be fashioned.

Having thus described the invention, what is'claimed is2 In a device for molding' a pipe, spaced inner and outer rings; securing elements upon the outer ring, projecting away from the axis of the outer ring; securing elements upon the inner ring, projecting toward the outer rings, said connections being adaptedA to be embedded in the material [which is y placed between the laggings and removable means upon the securingelements forengaging the laggings; thesecuring elements of the inner ring being severable adjacent said ring, to leave the ow line of the pipe unencumbered.

In testimony that I claim the foregoing as my own, l have hereto aliixed my signature in the presence of two witnesses.

WILLIAM BERRY.
